NOTE:
In dual-controller configurations, firmware on the two controllers is compared each time the
MSA chassis is restarted. If the versions are mismatched, the system prompts to clone the firmware
on the controller with the latest version over to the controller with the earlier version firmware. The
following message is displayed on the LCD panel of the controller with the earlier firmware:
07 CLONE FIRMWARE ? ‘<‘ = NO, ‘>’ = YES
Press the > button on the LCD panel to clone the firmware. During the cloning process, informational
messages are displayed on the controller LCD panels. When the cloning process is complete, the
just-updated controller automatically restarts.

Before resuming I/O access to the MSA, verify that the MSA and its storage arrays are online.
Disabling a controller for removal
In a dual-controller system, this command disables one of the controllers to prepare it for removal. When a
controller is disabled, all resources being processed by that controller are automatically failed over to the
remaining controller. After a controller has been successfully disabled, the LCD panel displays a message
stating that it is safe for that controller to be removed.
NOTE:
This command is available only in dual-controller configurations.
Basic command
disable other_controller
-or-
disable this_controller
-or-
disable standby
Overriding the ACU lock
To prevent simultaneous use of more than one management interface, the system automatically places a
lock on the MSA CLI whenever the Array Configuration Utility (ACU) or the Array Configuration Utility -
Command Line Interface (ACU-CLI) is managing the MSA.
This command can disable the lock and allow the CLI to be used at the same time that the ACU or ACU-CLI
is active.
CAUTION:
Turn off the ACU lock only under strict supervision. Multiple configuration sessions may lead to
contradictory commands, unintended configuration changes, inappropriate actions, or a disrupted status.
Basic command
override aculock
Enabling or disabling debug console logging
To allow additional system level messages to appear on the CLI console during failure events (such as hard
drive, power supply, or fan module failures):
Basic command
set debug
